How Does Laser Cutting Work?
4th March 2019

Laser cutting works by directing the output of a high-power laser most commonly through optics. The laser beam itself is a column of high intensity light. For CO2 lasers, the single wavelength is in the infrared part of the light spectrum and it's invisible to the human eye. The beam itself is only roughly 3/4 of an inch in diameter and this travels from the laser resonator, creating the beam through the machines beam path. It bounces in different directions off mirrors, or more professionally known as beam benders, finally focusing on the material that you’d like to cut. There is a nozzle that the focused laser beam goes through and also passing through this nozzle is a compressed gas, such as oxygen or nitrogen. The laser beam is focused by a special lens, or a curved mirror, taking place at the cutting head. Once the beam is precisely focused onto a single pinpoint, the heat density on that spot becomes heightened to an extreme level. Similarly to the concept of using a magnifying glass to focus the sun's ray onto an object to start a fire. There is a clever acronym for the word ‘laser’, five words which make it easier to define; Light Amplification by Stimulated Emission of Radiation.

This process is so accurate and time efficient, it has become a necessity for many businesses. Laser cutting is a stable, reliable, and very accurate cutting process that can save you time and money whilst boosting productivity. At CTR Lasers, each of our British CO2 laser cutting machines are designed for clean-cutting a wide range of organic materials including cloth, card, wood, plywood, leather, laminates, plastics, TPE and many others. In addition to the CO2 machines, CTR Lasers offer a rapidly increasing range of British designed and manufactured laser and engraving machines, these including metal cutting machines and microstep machines. We also offer advice, so if you’re not sure what the right machine is for you, or wish to know the benefits of each in more detail, we’d be glad to help.

CTR Lasers also lists a wide range of materials compatible with the machines and if the material isn't listed, just take advantage of the 'send a sample' service on any specialist materials for expert advice. To learn more about us and how we can help you, please call us today on 0844 800 4727 or drop an email to info@ctrfuture.co.uk and we’ll get back to you as soon as possible.
